I chose this picture for a few reasons as pertaining to the poem; firstly it rather mirrors the interior of my mind at least after first reading the poem; empty, baffled and somewhat confuused. But more importantly, I think it touches on the essence of the poem, which is to say it is similar to an empty room. It is open to the possibilities you put into it, and at first whatever you decide to make of it will be correct, and it is really how you evolve it to mean something that it grows and expands. I think the empty room and the poem go rather nicely together, and you can make whatever you want of them. Fourth Wall
